Let two consecutive numbers on the mile markers be "x" and "x%2B1"
if the sum of two consecutive numbers on the mile markers on the interstate is 661, we have
x%2Bx%2B1=661
2x=661-1
2x=660
x=330-> first number
x%2B1=331-> second number

For completeness, I'd like to make this notice: 

    330 is not necessary the FIRST number, as well as 331 is not necessary the SECOND number.


    The pair (331,330) is the other possible solution, where 

        331 is the first number, while 330 is the second number.
